摘要：
We report the synthesis of an ureido polymer containing 19-membered rings, prepared by the cyclopolymerization of a bifunctional monomer trans-1,2-bis(acryloyloxyethylureido)cyclohexane (TBAUCH) and studied for the selective adsorption of Ag+. PolyTBAUCH adsorbed Ag+ with an efficiency of 99.8%, and the maximum adsorption capacity was 39.8 mg/g. PolyTBAUCH selectively adsorbed Ag+ from an aqueous solution containing 20 different metal ions in similar concentrations. The selective adsorption depends on the controlling regioselective effect of the ring structure and the ureido groups. PolyTBAUCH could be reused at least for 5 cycles after desorption of Ag+ and maintained an Ag+ adsorption of 95.6% during the 5th cycle. Copyright © 2020 American Chemical Society.

摘要：
Four layered coordination polymers, namely, [Cd2(fuma)2(phen)2] (1), [Cd2(BDC)2(phen)2]·2DMF (2), [Cd2(NDC)2(phen)2]·0.5H2O (3), and [Cd2(NDC)2(bipy)2]·2DMF (4) have been synthesized under solvo-thermal conditions (fuma = fumaric acid, H2BDC = 1,4-benzenedicarboxylic acid, H2NDC = 1,4-naphthalenedicarboxylic acid, phen = 1,10-phenanthroline, bipy = 2,2′-bipyridine), which are composed of asymmetric/symmetric binuclear Cd2(RCOO)4(phen)2or Cd2(RCOO)4(bipy)2clusters as secondary building units (SBUs) linked by fuma2−, BDC2−, and NDC2−. Owing to the different steric hindrances of the di-carboxylates, the variation in Cd2(RCOO)4(phen)2SBUs showed an intriguing structural modulation, which was due to the carboxylates adopting dissimilar coordination fashions, while both the terminal phen co-ligands changed fromcis- totrans-position. Thus, this further induced twist angles (three neighbouring SBUs connected by the di-carboxylic acid) in the single layer of1-3varying from 109.7°, 132.3° to 180° (viewed along thea-axis) and correspondingly, three Cd2-SBU-based CPs exhibited structural evolution from an undulating to a lamellar layer. When the co-ligand bipy replaced phen,4also formed a lamellar layer framework based on the paddle-wheel Cd2(RCOO)4(bipy)2SBUs with bipy perpendicular to the layer rather than the slanted phen in3. The luminescence properties of1-4have also been explored, and their fluorescence emission mechanism of ligand-to-ligand charge transfer (LLCT) are confirmed by the time-dependent density functional theory (TDDFT) calculations. © The Royal Society of Chemistry 2020.

摘要：
To efficiently capture the toxic uranyl ions (UO22+), a new hierarchical micro-macroporous metal–organic framework was prepared under template-free conditions, featuring interconnected multi-nanocages bearing carbonyl groups derived from a semi-rigid ligand. The material exhibits an unusually high UO22+ sorption capacity of 562 mg g−1, which occurs in an intriguing two-steps process, on the macropore-based crystal surface and in the inner nanocages. Notably, the latter is attributed to the cooperative interplay of the shrinkage of the host porous framework induced by uranyl accommodation and the free carbonyl coordination sites, as shown by both single-crystal X-ray diffraction and a red-shift of the infrared [O=UVI=O]2+ antisymmetric vibration band. © 2019 Wiley-VCH Verlag GmbH & Co.

摘要：
A novel β-cyclodextrin functionalized silica gel (SAM-Si-β-CD) was prepared with grafting β-cyclodextrin (β-CD) to silica gel (Si-β-CD) containing salicylamide. It was characterized using XPS, SEM and FT-IR techniques. Variables of batch experiments including pH, temperature, contact time, interfering ions were studied. Langmuir, Freundlich isotherm and kinetic models were suitable to describe the adsorption process. The results showed that the equilibrium adsorption capacity was found to be 6.45mgg−1 respectively at pH 4.5, equilibrium time 60min and initial uranium(VI) concentration 25mg L−1. Additionally, SAM-Si-β-CD effectively adsorbed UO2 2+ in aqueous solution in the presence of interfering ions (Na+, Fe3+, Cu2+, Mg2+, La3+, Mn2+, Zn2+, Pb2+ and Hg2+). © 2016, Akadémiai Kiadó, Budapest, Hungary.

摘要：
By the reaction of different aromatic dicarboxylic acid with zinc nitrate, three metal-carboxylate frameworks, [Zn_3(BDC)_3(EtOH)_2](1), [Zn_3(BDC)_3(py)_2]·2DMF(2), and [Zn_3(NH_2-BDC)_3(H_2O)_2]·5DMF(3) which are constructed on the same linear trinuclear Zn_3(RCOO)_6 secondary building units, have been synthesized and characterized by X-ray diffraction analyses. Structural analyses showed that there are terephthalic acids as ligand linkers to form the hxl topological layer structures for 1 and 2. The introduction of the rigid aromatic ring pyridine in 2 as the terminal co-ligand of Zn_3-SBU to instead of the flexible ethanol in 1, will form the layer-pillared supramolecular systems with 2-D crisscross channels, through its π-π stacking interactions. Owing to the steric hindrance of amino groups, 3 was assembled into a three-dimensional porous structure with pcu topology derived from the 2-amino-terephthalic acid as linkers to connect the Zn_3-SBUs through a head-to-tail type.

摘要：
The adsorption of Th(IV) was studied using a novel dibenzoylmethane molecular imprinted polymers, which was prepared using acryloyl-β- cyclodextrin as a monomer on surface modified functional silica gel. X-ray photoelectron spectroscopy and FTIR were employed to confirm the reliability of the synthetic polymer. Scanning electron microscope was used to analyze the surface properties of the experimental materials. UV-spectrophotometer was employed to investigate the adsorption property and the concentration of Th(IV). Adsorption kinetics and adsorption isotherm were carried out. In pH 3.5, the adsorption equilibrium could reach a balance in 45 min, the resultant adsorbing capacity was 30.8 mg g-1, and the remove ratio of Th(IV) was 88.1 %. © 2012 Akadémiai Kiadó, Budapest, Hungary.

摘要：
A simple and efficient protocol was developed for the syntheses of optically active epoxides(2a-2d) via the reactions of epichlorohydrin with organometallic reagents with steric hindrance at low temperature. On this basis, episulfides(3a-3d) were obtained with high e.e. values by the reaction of the corresponding epoxides with NH4SCN. The configuration of thiiranes was opposite to that of the corresponding epoxides. Then, epoxides 2a-2d were anionically polymerized and the poly-R-2a(or poly-S-2a) was proved to keep a stable one-handed helical conformation in solution. The oligomers[degree of polymerization(DP)=2-5] were obtained when the thiiranes(3a, 3b and 3c) were used to polymerize. © 2013 Jilin University, The Editorial Department of Chemical Research in Chinese Universities and Springer-Verlag GmbH.

摘要：
5-亚甲基二苯并[a,e]-环庚烷(2a)和5-亚甲基二吡啶并[1,2-b:5,4-b’]环戊烷(2b)分别应用两种不同的方法合成.方法一是通过酮与三苯基甲基溴化鳞反应(Wittig法)制备,方法二是通过酮与格氏试剂反应后再在酸性条件下发生消除反应制备.后者原料便宜,操作简单且产率高,是合成此类1,1-二取代乙烯的好方法.通过元素分析及NMR对产物的结构进行了表征.
